The episode as NWS PHI wrote it up.
Strong to high west to northwest winds affected Eastern Pennsylvania from the evening of the 18th through the evening of the 19th. Peak wind gusts averaged around 55 mph. The winds tore down trees, tree limbs and wires and caused power outages. Over 120,000 homes and businesses lost power. All power was restored by the morning of the 21st. It was surmised that the wet soil from the recent snow melt made it easier for trees to be toppled. The stronger winds began following a cold frontal passage on the evening of the 18th. The strong to high winds reached their peak speeds during the late morning and afternoon of the 19th and then slowly decreased during the evening and overnight on the 19th.
In Monroe and Pike Counties, about 6,000 Pennsylvania Power and Light customers lost power. In the Lehigh Valley, about 11,000 Pennsylvania Power and Light customers lost power with a five to one ratio between Lehigh and Northampton Counties. In Lehigh County, in Allentown, the high wind stripped the aluminum facade off a business on Tilghman Street, tore signs down from two other businesses and tore lose a banner at the top of the Wachovia Bank and 7th and Turner Streets. Upper Macungie Township suffered the most power outages in the county. In Berks County, about 5,000 Metropolitan Edison customers lost power. In Birdsboro, the high winds caused the collapse of two burnt out buildings on North Furnace Street. In Boyertown, seven poles were knocked down.
In the Philadelphia Metropolitan Area, about 97,000 PECO Energy customers lost power with Bucks County the hardest hit. The number of customer outages at 6 p.m. EST that evening was down to 19,000. In Bucks County, a family of seven in Bristol Township had to be relocated after a tree fell through the roof of their Balsam Road home. In Falls Township, a piece of a roof was torn off an industrial building on Ridge Drive and damaged two vehicles. In Langhorne, a downed tree shorted wires which caused appliance damage to a home. In Doylestown, a store's equipment was damaged from a similar surge. The Parx horse racing card in Bensalem was cancelled. In Montgomery County, in Douglass Township, the roof of an apartment building on Market Road was partially torn away. Snapped poles occurred in Lower Pottsgrove Township. All Delaware River Bridges in the local Philadelphia area had speed reductions and banned empty tractor-trailers through the evening of the 19th.
Peak wind gusts included 61 mph in Kennett Square (Chester County), 60 mph in Forks Township (Northampton County), 58 mph in Reading (Berks County), 56 mph in Drexel Hill (Delaware County), 55 mph at the Philadelphia International Airport, 53 mph in Mount Pocono (Monroe County), 52 mph in Doylestown (Bucks County), 51 mph in Coatesville (Chester County), Willow Grove (Montgomery County) and the Lehigh Valley International Airport.| |The strong to high winds were caused by the large pressure difference between a strong high pressure system building into the United States from central Canada and a low pressure system in the Canadian Maritimes. Winds started decreasing when the low pressure system moved east of the Canadian Maritimes on the night of the 19th and the high pressure system reached the Great Lakes.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
612 PM EST FRI FEB 18 2011
.SYNOPSIS...
A STRONG COLD FRONT WILL CROSS THE REGION TONIGHT. HIGH PRESSURE
WILL BUILD INTO THE REGION THROUGH SATURDAY BEFORE SLIDING
SOUTHEAST SUNDAY. LOW PRESSURE APPROACHING FROM THE WEST SUNDAY
NIGHT WILL PASS THROUGH OUR AREA ON MONDAY. ANOTHER LOW MAY CROSS JUST
TO OUR SOUTH ON MONDAY NIGHT INTO TUESDAY. HIGH PRESSURE WILL THEN
RETURN FOR THURSDAY.
&&
.NEAR TERM /THROUGH SATURDAY/...
CLOUDS EXITED THE REGION FAIRLY QUICKLY THIS AFTERNOON AND
TEMPERATURES RESPONDED QUITE RAPIDLY. A COUPLE OF RECORDS WERE
REACHED THIS AFTERNOON (RDG AND ACY SO FAR) AND THERE MAY BE ONE
OR TWO MORE AFTER THE DAILY CLIMATE HAS BEEN RUN LATER TODAY.
TONIGHT WILL BE A RELATIVELY NICE NIGHT ALTHOUGH WINDS WILL REMAIN
ACROSS THE REGION THROUGH THE EVENING BEFORE TAPERING A BIT FOR
THE OVERNIGHT HOURS. THE COLD FRONT WILL CROSS THROUGH THE REGION
TONIGHT BUT IT IS PRETTY DRY AND NO PRECIPITATION IS EXPECTED.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
THE COLD FRONT MOVES AWAY FROM THE AREA RATHER QUICKLY AND IN ITS
WAKE WE HAVE STRONG CAA AND VERY GUSTY WINDS. IN THE MORNING, AS THE
SUN RISES, THE WINDS ALOFT SHOULD BE ABLE TO MIX DOWN TO THE
SURFACE. THE MODEL GUIDANCE SHOWS WINDS IN EXCESS OF 50 KNOTS AT 925
MB AND 850 MB AS WELL AS THE 500 MB JET MOVING DIRECTLY OVER OUR CWA
ON SATURDAY. IT ALSO LOOKS LIKE THERE WILL TWO PUSHES OF GUSTY
WINDS. THE INITIAL PUSH WILL BE IN THE MORNING WITH THE JET AND A
SECOND PUSH LOOKS TO BE TOWARD LATE AFTERNOON/EVENING AS THE WE
START TO SEE DECENT 3 HR PRESSURE RISES. AS A RESULT, WE HAVE A
HIGH CONFIDENCE OF A DEFINITE HIGH END WIND ADVISORY EVENT.
HOWEVER, THE LAST EST MODEL DATA ALSO SUGGESTS THAT WE WILL HAVE
THE POTENTIAL FOR A LOW END WIND WARNING EVENT, ALTHOUGH
CONFIDENCE IS NOT AS HIGH AS WE WOULD LIKE IN ORDER TO ISSUE A
HIGH WIND WARNING WITH THIS PACKAGE. WITH ALL OF THIS IN MIND WE
HAVE DECIDED TO RAISE A HIGH WIND WATCH FOR THE ENTIRE CWA FOR
SATURDAY AND LET THE NEXT SHIFT GET A BETTER LOOK AT THE WINDS AS
THEY APPROACH THE REGION.
ALONG WITH THE STRONG WINDS SATURDAY...LOW AFTERNOON RELATIVE
HUMIDITIES AND DRY FUELS WILL LEAD TO ENHANCED FIRE WEATHER
CONDITIONS. SEE THE FIRE WEATHER SECTION BELOW.
ALSO, AS A RESULT OF THE STRONG CAA WE MAY SOME FLURRIES ACROSS
THE NORTHERN ZONES AS THE FETCH WILL EXTEND ALL THE WAY FROM THE
GREAT LAKES.
WINDS SHOULD START TO COME DOWN SATURDAY NIGHT AND WILL BE MUCH
LESS OF A PROBLEM ON SUNDAY AS THE HIGH SLIDES ACROSS TO OUR
SOUTH. THE HIGH WILL BE IN CONTROL FOR SUNDAY.
LOW PRESSURE WILL APPROACH THE REGION FROM THE WEST LATE SUNDAY
AND MOVE THROUGH OUR AREA ON MONDAY. A WARM FRONT LOOKS TO MAKE
ITS WAY NORTHWARD IN THE REGION WHICH WILL ALLOW THE TEMPERATURES
TO WARM INTO THE 50S DURING THE DAY ON MONDAY. A SECONDARY LOW FORMS
ALONG THE COLD FRONT BOUNDARY, CROSSING OUR AREA LATE MONDAY INTO
MONDAY NIGHT. PRECIPITATION LOOKS TO BE A MIX AT THE MOMENT, WITH
MORE DETAILS COMING THE THE NEXT COUPLE OF DAYS.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/...
PRECIP WILL END ERLY IN THE PD, AND A LARGE AREA OF HIGH PRESSURE
WILL BUILD IN FROM THE NORTHWEST ON TUE AND REMAIN OVER THE REGION
THRU THURSDAY. AS A RESULT, THIS PERIOD LOOKS TO BE DRY. AS THE LOW
MOVES EWD, TEMPS WILL REBOUND NICELY FROM VERY COLD ON TUES TO
AROUND NRML ON WED AND ABV NRML ON THU.
THERE ARE SOME TIMING DIFFS WITH THE APPROACH OF THE NEXT SYS BY
FRIDAY. THE ECMWF IS FASTER BRINGING PRECIP IN FROM THE W BY LATER
THU, WHILE THE GFS HOLDS THINGS OFF UNTIL FRIDAY. HOWEVER, BOTH
MDLS INDICATE PRECIP, MAINLY IN THE FORM OF RAIN, OVER THE REGION ON
FRIDAY. FOR NOW, WILL SPLIT THE DIFF BTWN THE MDLS AND GO WITH LOW
CHC POPS THU NIGHT INTO FRI AND SEE IF BETTER AGREEMENT IS REACHED
IN THE NEXT FEW DAYS.
&&
.AVIATION /23Z FRIDAY THROUGH WEDNESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
THE WIND WILL BE THE BIG ISSUE WITH THE TERMINALS IN THE UPCOMING
TAF PACKAGE AS IT IS OTHERWISE VFR. A COUPLE OF ISOLATED SHOWERS
HAVE DEVELOPED ACROSS THE AREA LATE THIS AFTERNOON AND MOST SHOULD
MISS THE TERMINALS. WE INCLUDED A TEMPO GROUP EARLY IN KTTN AND
KILG AND WILL AMEND ACCORDINGLY ELSEWHERE IF NECESSARY.
SHOWERS ARE PRECEDING A VERY STRONG COLD FRONT AND THERE ARE MID
AND HIGH LEVEL CLOUDS PRECEDING IT ACROSS PA THAT WILL BE PASSING
ACROSS OUR TERMINALS MAINLY THIS EVENING. WINDS INTO THE
OVERNIGHT SHOULD BE FROM THE WEST AND AVERAGE 10 TO 15 KTS. NO
GUSTS WERE INCLUDED PRE COLD FRONTAL. WE STARTED GUSTS BEHIND THE
COLD FRONT LATER TONIGHT AND REMOVED MOST OF THE CLOUDINESS.
WEST TO NORTHWEST WINDS SHOULD REALLY INCREASE DURING THE DAY ON
SATURDAY WITH SUSTAINED SPEEDS AVERAGING 20 TO 30 KNOTS AND PEAK
GUSTS BETWEEN 40 AND 50 KNOTS. WE HAVE OPTED FOR THE DRIER MODEL
GUIDANCE AS TO WHAT WOULD BE VFR STRATOCU COVERAGE DURING THE DAY
ON SATURDAY.
WINDS SHOULD START DECREASING SATURDAY EVENING, BUT IN ALL
LIKELIHOOD SOME GUSTINESS SHOULD CONTINUE INTO THE NIGHT. WHAT
STRATOCU CLOUDS THERE WILL BE SHOULD BE GONE BY SUNSET.
OUTLOOK...
VFR CONDITIONS ARE EXPECTED FOR SATURDAY NIGHT AND MOST OF SUNDAY.
WINDS WILL SUBSIDE ON SUNDAY.
MODELS INDICATE TWO SEPARATE SYSTEMS MAY AFFECT PORTIONS OF THE CWA
SUNDAY NIGHT AND AGAIN MONDAY NIGHT, WITH THE FIRST ONE PASSING BY
TO OUR NORTH AND THE SECOND ONE PASSING BY TO OUR SOUTH. MVFR
CONDITIONS ARE POSSIBLE WITH THE FIRST...AND IFR CONDITIONS ARE
POSSIBLE WITH THE SECOND. STAY TUNED.
&&
.MARINE...
A COLD FRONT WILL MOVE OFFSHORE THIS EVENING...BUT THE STRONGEST
WEST TO NORTHWEST WINDS WON/T KICK IN UNTIL JUST BEFORE SUNRISE,
THEN CONTINUE THROUGH SATURDAY. THEN A GRADUAL DECREASE IN WIND
SPEEDS BEGINS SATURDAY EVENING, BUT GUSTS OVER 30 KT ARE STILL
POSSIBLE INTO SUNDAY MORNING. GALE WARNINGS THAT WERE HOISTED EARLY
THIS MORNING WILL CONTINUE AS POSTED, BUT IT IS POSSIBLE THAT STORM
WARNINGS MAY BE NEEDED ON SATURDAY IF ENOUGH MIXING TAKES PLACE,
AND/OR IF THE PRESSURE GRADIENT TIGHTENS JUST A LITTLE BIT MORE THAN
CURRENTLY EXPECTED.
AFTER A BRIEF RESPITE SUNDAY...LOW PRESSURE MOVING THROUGH OR JUST
NORTH OF OUR NORTHERN WATERS SUNDAY NIGHT INTO EARLY MONDAY MORNING
MAY RESULT IN NEAR GALE FORCE WIND GUSTS FROM THE SOUTHWEST.
FINALLY...ANOTHER LOW PASSES THROUGH OUR JUST SOUTH OF OUR SOUTHERN
WATERS MONDAY NIGHT INTO TUESDAY. AGAIN...GALE FORCE WINDS ARE
POSSIBLE WITH THIS SYSTEM.
&&
.FIRE WEATHER...
RED FLAG CONDITIONS ARE EXPECTED TO OCCUR ACROSS SOUTHERN NEW
JERSEY, DELAWARE AND THE EASTERN SHORE OF MARYLAND AS GUSTY
NORTHWEST WINDS AND LOW RELATIVE HUMIDITIES COMBINE WITH LOW LEVEL
FUEL MOISTURE ON SATURDAY. IT WILL BE VERY WINDY WITH NORTHWEST
WINDS GUSTING TO 40 TO 50 MPH WITH SOME LOCALLY HIGHER WINDS
POSSIBLE. AFTERNOON RELATIVE HUMIDITIES OF 25 TO 30 PERCENT IN
THE STRONG COLD AIR ADVECTION ARE ALSO EXPECTED TO OCCUR.
THE REG FLAG WARNING IS IN EFFECT FROM 9AM TO 9PM ON SATURDAY.
PLEASE SEE THE WARNING STATEMENT FOR FURTHER DETAILS.
&&
.TIDES/COASTAL FLOODING...
THE TIDE OF INTEREST IS THE LOW TIDE CYCLE SATURDAY AFTERNOON INTO
SATURDAY EVENING. AT THAT TIME...WEST TO NORTHWEST WINDS SHOULD
RESULT IN BLOWOUT TIDES ON THE OCEAN...AND A BIT LATER ON THE
DELAWARE BAY AND EVENTUALLY DELAWARE RIVER. STORM SURGE GUIDANCE
SHOWS LEVELS DROPPING TO BETWEEN 2 AND 3 FEET BELOW MLLW DURING THAT
TIDE CYCLE. A LOW WATER ADVISORY HAS BEEN ISSUED FOR THE OCEAN AND
DELAWARE BAY. BLOW OUT TIDES WILL ALSO BE A PROBLEM ON THE TIDAL
SECTIONS OF THE DELAWARE RIVER AND AN SPS WILL BE ISSUED FOR THAT
AREA AS WE GET CLOSER TO THE EVENT. IN THE MEANTIME...A MENTION HAS
BEEN PLACED IN THE HWO FOR THE TIDAL SECTIONS OF THE DELAWARE RIVER.
&&
.CLIMATE...
THESE ARE THE RECORD HIGH TEMPERATURES FOR TODAY, ALONG WITH THE
HIGHS THAT HAVE OCCURRED THROUGH 3PM THIS AFTERNOON:
